Even if it isn't, it's unreasonable to expect the world to stop spinning in the interim.
If a superintelligent AGI is born tomorrow, it might just establish itself as a singleton, prohibit other AGIs from exisiting, and then take an indefinite vacation. If that happens, we'll continue to work on seemingly mundane, non-important problems (such as this one) for humanity's foreseeable future.
Don't forget that Google owns DeepMind. If there was a way to divine who's closest to AGI at the present time, the answer would probably be them (even if arrival is ultimately far off).
So is working on antigravity, free energy, and backwards time travel, but people don't do that because they are no reasonable approaches we can try.
Glorifying "AI AI AI" is silly because — there are no approaches we can try. Sure, we can identify ten million images per second, but none of that involves the least bit of "thinking."
Get back to us when you have an algorithm for love and art and petrichor.
I'm not naive enough to think that it can be solved in a short time. I do think that it is worth it for a person to spend the rest of their life working on it. There is just nothing more exciting than AI in my opinion.
Just imagine the possibilities...

"Deep" AI (self-directed / human-interactive) will take more time and effort, and can have (simulated) emotions if so programmed; the determinate is how to sell such as a viable product or service that doesn't freak people out too much or do something stupid like place untrustworthy systems in charge of live nuclear missiles.
